Takeuchi TB135 Parts Catalog

Every time a customer rolls a TB135 into the bay with a torn hydraulic line or a worn track roller, the first thing I need is the right part number. Aftermarket catalogs spit out wrong numbers, mismatched supersessions, or plain missing data. This 628-page Takeuchi TB135 Parts Catalog is the OEM factory print – not a re-indexed PDF. If you’ve ever ordered a seal that was 2mm too small, you know why this matters.

Book No. BG4Z004 covers serial numbers from 13510004 onward. That means every revision Takeuchi made after that break point is in here. The manual doesn’t wallpaper generic illustrations; it gives you the exact exploded view with the part number right next to the callout, like you see on page 3 with the travel lever and swing pedal assembly – bolts, washers, pins, seals, every single fastener listed by part number and length.

I’ve got a stack of third-party lists on my shelf that I wouldn’t use to shim a workbench. This one earns its place next to the torque wrench. Seven system chapters plus a full parts index at the back. The index alone is worth the download – you can look up any bolt, nut, or washer by its part number prefix and jump straight to the illustration.

UNDERCARRIAGE: Track Rollers and Sprockets

Chapter 1 covers the undercarriage. Idlers, sprockets, track chains, carrier rollers – all laid out with Takeuchi’s own callout numbers. If you’re rebuilding a final drive or replacing a rail group, this is where you confirm the part number before ordering. The manual includes bolt torque callouts? No, it’s a parts catalog, not a service manual. But it lists every bolt by size and grade so you can cross-check against the workshop specs. Pair this with a Takeuchi TB125 TB135 TB145 Workshop Manual for the torque values and you’ve got a complete work package.

ENGINE & ELECTRICAL SYSTEM: Two Engine Variants Covered

Chapter 3 is the one most people need first. The TB135 came with either a 3TNE88-(E)TB(1) or a 3TNV88-QTB/QTB1/QTB2 engine. The manual splits those into separate sections inside chapter 3, each with its own parts index. The electrical system – alternator, starter, wiring harness, switches – is included in the same chapter. Don’t guess which glow plug fits a 3TNV88; the part number is right there in the engine electrical breakdown. Aftermarket catalogs often merge these two engines into one generic list. That’s how you end up with a starter that doesn’t clock correctly.

Takeuchi designed the TB135 with a tight engine bay. Using the wrong part number means pulling the whole power unit again. This catalog eliminates that second teardown. The exploded views show orientation, bracket placement, and fastener count. I’ve watched guys save an hour just by confirming the alternator bracket carries a different bolt length on the intake side versus the exhaust side – it’s in the drawing.

HYDRAULIC PIPING & TANK: Make Sure You Get the Correct Tube Assembly

Hydraulic hoses and tubes are serial-number specific on these machines. Chapter 4 covers the hydraulic piping and tank. If your customer’s machine is between serial numbers 13510004 and, say, an early 13520000, the piping layout might use a different pre-formed tube. The manual’s illustration notes the serial number break for each tube assembly. You don’t have to call the dealer and wait on hold; you look at the page, match the serial, and order.

This is also where you’ll find the tank assembly – strainer, filler cap, return filter. Each component has its own part number. There’s no “compatible with” language. Takeuchi’s part number is the only one that fits the mounting tabs and the O-ring groove depth. If you’ve ever had a return filter housing leak because the aftermarket cap didn’t seat right, you know exactly what I’m talking about.

Why You Need the Parts Index at the Back

Flip to the “Parts index” section after the eight chapters. It’s a multi-page alphabetical listing of every part number in the catalog. Say you salvaged a bolt out of a parts machine and the head is stamped 00002-00204. You cross that number in the index, and it tells you which chapter and figure shows that bolt. From there you can verify the length and grade. That same index also works in reverse – if you know the bolt length but not the number, you can scan the chapter illustrations for a matching callout. This is the kind of tool that keeps you from ordering the wrong fastener three times.

And because this is an OEM catalog, the part numbers haven’t been re-indexed by a third party. Takeuchi TB135 Parts Catalog from AutoRepairManuals is the exact same file Takeuchi dealers use. No guesswork, no “comparable to” listings. You order the number on the page, and it arrives fitting.

7 System Chapters and One Parts Index

Here’s a quick walkthrough of the chapter layout so you know exactly what you’re getting:

• Chapter 1 – UNDERCARRIAGE: track frame, final drive, sprocket, idler, roller assemblies
• Chapter 2 – TURNTABLE & CONTROL LEVER: swing gear, travel lever, swing pedal, control valve linkages
• Chapter 3 – ENGINE & ELECTRICAL SYSTEM: two engine variants, starting/charging system, wiring harness
• Chapter 4 – HYDRAULIC PIPING & TANK: lines, tubes, tank, filter, fittings
• Chapter 5 – COVER & CAB: hood, floor plate, seat, console, ROPS structure
• Chapter 6 – HOE ATTACHMENT: boom, arm, bucket, bucket cylinder, pins
• Chapter 7 – DECAL & TOOL: caution decals, tool kit contents
• Chapter 8 – HYDRAULIC DEVICE: pump, control valve, swing motor, travel motor breakdowns

That’s the full list. Each chapter opens with a table of contents for its sub-sections. For example, in Chapter 3 you’ll see separate entries for the 3TNE88 and 3TNV88 engines. You don’t have to guess which page to turn to. The PDF is all original – multi-language (English, Japanese, French, German) but the part numbers are universal.

Order Parts Without Calling a Dealer

Once you have this catalog, you can order parts online or over the counter with confidence. Provide the part number, the machine model and serial number, and the quantity. The manual even includes the ordering instructions in multiple languages (see page 2 of the PDF). It tells you exactly what information the dealer needs: machine model, serial number, part number, part name, quantity. No back-and-forth phone calls.

Keep in mind that this is a parts catalog, not a service or repair manual. It does not contain removal/installation instructions, torque specs, or diagnostic procedures. For that, you’ll need the corresponding workshop manual. But when you need to know the exact part number for a boom pin seal or a fuel injector, this is the only source that won’t send you chasing ghosts.

A lot of guys ask me if the exploded views are clear enough to identify what’s missing. The answer is yes – Takeuchi uses clean line drawings with leader lines to numbered callouts. The part number table sits below the figure. If you see a seal in the drawing but no callout number, it’s not a separate part – it comes with the assembly. That information alone saves you from ordering a seal kit when you only needed the O-ring.

For background on how parts catalogs fit into the broader industry, Automotive Industry Overview provides a solid context. And the general concept of original equipment documentation is well described in the Automotive Industry Overview article.

FAQ

Is this manual in English?

Yes. The PDF includes English, Japanese, French, and German. All part numbers are language-independent.

Does it cover the electrical wiring diagrams?

No. This is a parts catalog – it shows the alternator, starter, and harness as assemblies with part numbers but does not include pinout diagrams or circuit schematics. Those are in the service manual.

What if my serial number is before 13510004?

This book covers from S/N 13510004 onward. Earlier machines used different part numbers, and you would need the manual specific to that serial range.

How do I find the part number for the hydraulic pump?

Go to Chapter 8 – HYDRAULIC DEVICE. The pump assembly is illustrated with a callout number. Cross-reference that callout to the part number table next to the figure. Confirm the serial range in the note next to the figure – some pump variants were installed at different break points. Order by that number and your dealer will get it right.

Takeuchi TB135 Parts Catalog

If you’re ordering parts for a TB135 from a generic aftermarket list, you’re going to get the wrong part. I’ve seen it happen. A guy brings in a hydraulic pump seal that doesn’t match the port face because the online seller listed a “universal” number. That costs you time, cash, and a customer pissed off that his mini-ex is down another day. This Takeuchi TB135 Parts Catalog is the factory-issued book – 628 pages, OEM part numbers, exploded diagrams, and cross‑references for both the 3TNE88 and 3TNV88 engine families. If you turn wrenches on compact excavators, this is how you order correctly the first time.

Engine & Electrical System: What You Get

Section 3 covers the ENGINE & ELECTRICAL SYSTEM. Inside that chapter you’ll find the breakdown for two separate engine lines: 3TNE88-(E)TB(1) and 3TNV88-QTB, QTB1, QTB2. Each engine section has its own contents and parts index. The electrical side includes starter, alternator, wiring harness details – with factory part numbers you can hand to any dealer counter. No guessing which relay fits which year. The manual also lists the serial number break point (S/N 13510004-) so you know exactly which revision your machine matches.

Undercarriage Parts Breakdown

Chapter 1 – UNDERCARRIAGE – gives you the track frame, sprocket, idler, roller, and track shoe assemblies. Each illustrated page has a figure number and a table with the part number, description, quantity, and compatibility notes. See the “AR” notation for optional parts. Page 4 of the manual explains the symbology: (W) for retrofitted part numbers, (Y) for superseded numbers, (R)/(L) for right and left. If you need a final drive seal or a track adjuster assembly, you look here first.

Hydraulic Piping & Tank – Real Names, Real Numbers

Chapter 4 – HYDRAULIC PIPNG & TANK (yes, they spelled it PIPNG in the original – that’s the factory file) – covers all hoses, tubes, fittings, and the hydraulic oil reservoir. The parts are grouped by functional circuit. The manual clearly shows which o‑ring goes where and gives the actual Takeuchi part number. Aftermarket cross‑reference sites often swap metric and SAE thread sizes; this catalog uses only factory dimensions. You order by the number printed on the page, not what some forum guy guessed.

Why This Parts Catalog Beats Aftermarket Lists

I’ve dealt with third‑party parts catalogs that reprint blurry screenshots from a 2003 PDF. They leave out the supersession notes and compatibility flags. This OEM catalog includes the “How to read the parts manual” section (pages 2–5 of the PDF) that explains every symbol: the (*) for parts with restricted availability, the (AR) for as‑required items, and the compatibility letters. Aftermarket sources don’t give you that. You also get the full parts index at the back – 628 pages of organized data. You want a part number for a hoe attachment bushing? Chapter 6 – HOE ATTACHMENT. Need a decal or safety sticker? Chapter 7 – DECAL & TOOL. It’s all there.

Does This Manual Cover Both 3TNE88 and 3TNV88 Engines?

Yes. The Engine section lists two sub‑assemblies: 3TNE88-(E)TB(1) and 3TNV88-QTB, QTB1, QTB2. Each engine type has its own table of contents and separate parts index. If your TB135 was built before a certain serial number or after, the manual tells you which parts apply. The electrical system diagrams are also split by engine variant. Always check the serial number on your machine (stamped on the turntable frame) before ordering – the manual references S/N 13510004- as the starting point for this book number BG4Z004.

Can I use this parts catalog to rebuild the engine?

No. This is a parts catalog, not a service manual. It gives you part numbers and diagrams, not torque specs or assembly steps. For repair procedures you need a workshop manual like the Takeuchi TB125 TB135 TB145 Workshop Manual.

How do I find the correct part number if my machine has a serial number below 13510004?

This book number BG4Z004 covers serial 13510004 and above. If your machine is older, you need the earlier edition parts catalog. The manual’s introduction clearly states the serial break. Always verify your machine’s serial number against the cover page before ordering. The parts index at the back lists every component by name and number; cross‑reference with the exploded illustration to confirm fitment. If you still have doubt, call a Takeuchi dealer with the serial and the part description – they can pull the superseded number from their own system.

Does the manual include wiring diagrams?

Yes, within the ENGINE & ELECTRICAL SYSTEM chapter there are wiring harness illustrations and connector part numbers. It’s not a full electrical troubleshooting guide, but it shows the routing and connector IDs so you can order the correct harness section.

What is the difference between this parts catalog and the Takeuchi TB135 Parts Catalog listed on another site?

There is only one official TB135 parts catalog from Takeuchi – 628 pages, OEM, book number BG4Z004. Any site claiming a different version is either a reprint of the same file or a third‑party compilation. Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual is for a different machine. Stick with factory‑sourced documents to avoid mismatched part numbers.

Look over the table of contents and compare it to any aftermarket list you’ve used. The eight main chapters cover every system: undercarriage, turntable, engine/electrical, hydraulics, covers/cab, hoe attachment, decals, and hydraulic devices. Each part number ties directly to Takeuchi’s inventory. For the Automotive Industry Overview you’ll see why OEM documentation matters – the same principle applies to construction equipment: factory specs eliminate ambiguity. Automotive Industry Overview references the broader context of standardization. If you’re tired of ordering wrong parts, get the factory file. Download the Factory Manual now.
